Antibiotics are more efficient when they can act on their target directly at the site of infestation, without dilution. In the journal Angewandte Chemie, American scientists describe a synthetic chemical trap that propels itself to its place of action in the body fluid and then lures the bacteria into its interior to poison them. One of the main functionalities of the microdevice is the communication with its target, says the study.
Factory halls, airport terminals and high-rise office buildings are often equipped with automated "anticipatory" heating systems. These work with pre-defined scenarios specially calculated for the building and help save building owners a great deal of heating energy. However, such an individual programming is too expensive for individual apartments and private homes.
The first UK consumer study on the use of Bambara Groundnut as an ingredient in products has shown that sharing information on its sustainable features increased consumers' positive emotional connection to food.
Researchers from the University of Nottingham's School of Biosciences tested Biscotti and crackers made with Bambara groundnut against standard commercial products. The study published in Food Research International showed that the main driver for accepting this new ingredient was how people felt when given information about its sustainability credentials.
BINGHAMTON, N.Y. - New research led by faculty at Binghamton University, State University of New York, could aid cleaner energy technologies.
The atomic reaction between gases and oxides is a key piece for many technological puzzles. It can lead to benefits such as better catalysts to enable cleaner energy technologies, or to problems like corrosion.
Understanding those interactions isn't always easy, though, and often doesn't go beyond the surface -- quite literally.
Were you born in an H1N1 year or an H3N2 year? The first type of influenza virus we are exposed to in early childhood dictates our ability to fight the flu for the rest of our lives, according to a new study from a team of infectious disease researchers at McMaster University and Université de Montréal.
Chemotherapy used to shrink a tumor before surgery, called neoadjuvant chemotherapy, is becoming more common in many cancers, including stage II and III rectal cancer. However, the chemotherapy regimens FOLFOX and CapeOx used in this setting come with significant side effects, to the degree that many patients are unable to complete the recommended schedule.
Research reveals consumers don't simply rely on other peoples' opinions in reviews but leverage a combination of reviews and previews when purchasing e-books.
The purchase likelihood escalates 31% when consumers are exposed to both e-book previews and reviews.
Purchase likelihood is between 7 and 17% when consumers are exposed to either e-book previews only or online reviews only.
FAYETTEVILLE, Ark. - Role-playing the administrative experiences of immigrants led students to empathize and trust them, according to a new study by two University of Arkansas researchers.
Brandon Bouchillon, assistant professor in the School of Journalism and Strategic Media, and Patrick Stewart, associate professor in the Department of Political Science, created a role-playing experience for students to learn what the process of applying for citizenship might be like for immigrants. The experience was integrated into an online American Government class.
The existing characterization procedures to evaluate emerging photovoltaic devices are not appropriate for halide perovskite solar cells, a new generation of solar cells called to overcome the present state-of-the-art technologies. A vast group of scientists with Prof. Pavel A. Troshin representing Skoltech has reached a consensus on the suitable procedures and the variables to be reported in stability studies of this kind of solar cells.
There is plenty of data showing that police brutality leads to mistrust of police and law enforcement. Researchers from Lehigh University and the University of Minnesota set out to see if experience with police brutality might affect health by causing mistrust in medical institutions.
Through an analysis of data gleaned from a survey of 4,000 people living in urban areas about their experiences with police brutality, they found that there is a relationship between police brutality and mistrust in medical institutions.
LOS ANGELES (Jan. 29, 2020) -- A new study from the Smidt Heart Institute at Cedars-Sinai and other centers nationwide shows that patients who underwent a minimally invasive transcatheter aortic-valve replacement (TAVR), had similar key 5-year clinical outcomes of death and stroke as patients who had traditional open-heart surgery to replace the valve.
EAST LANSING, Mich. - While political polarization in the United States is the worst it has been in years, new research from Michigan State University and the Max Planck Institute for Demographic Research suggests that having a partisan - and sometimes divisive - Congress might be more productive than if bipartisan groups were the norm.
Billions of cardiac muscle cells are lost during a heart attack. The human heart cannot replenish these lost cells, so the default mechanism of repair is to form a cardiac scar. While this scar works well initially to avoid ventricular rupture, the scar is permanent, so it will eventually lead to heart failure and the heart will not be able to pump as efficiently as before the damage caused by heart attack.
New clinical guidelines call strongly for providing psychosocial supports for children and adolescents with complex attention-deficit/hyperactivity disorder (ADHD). Developed by the Society for Developmental and Behavioral Pediatrics (SDBP), the guideline provides a framework for diagnosing and treating complex ADHD in these age groups.
The human brain's ability to recall a single movement is significantly affected by the characteristics of previous actions it was learned with, a new study has shown.
Research led by the University of Plymouth explored how distinct prior actions affected a person's ability to perform certain simple movements, corresponding to, for example, reaching to catch a ball or drinking a cup of coffee.
